c-ummins Injector N14 Series (Part Number: 3411767T) Product Details

The c-ummins 3411767T fuel injector is a high-performance, OEM-upgraded finished electronic unit injector exclusively engineered for the c-ummins N14 Celect, Celect Plus & STC 14L diesel engine platform (1991–2006), with specialized compatibility for N14 420-450HP heavy-duty models—ideal for high-demand industrial and transportation applications that require enhanced stability and efficiency. As a fully optimized, factory-calibrated finished product, it boasts three core competitive features tailored for rigorous ultra-heavy-duty operations: enhanced compatibility adaptability, upgraded durability & sealing, and Intertek-verified OEM-level manufacturing quality, all engineered to meet or exceed c-ummins’ global quality standards, ISO 9001 certification requirements, and the strict quality control protocols of c-ummins’ global manufacturing facilities including CCEC, DCEC, and GCIC. Adhering to c-ummins’ OEM design specifications and intelligent manufacturing processes—including advanced equipment such as AVL hot test benches, ABB automatic robots, and precision testing instruments (Zeiss, Mahr) in c-ummins’ advanced quality laboratories, six sigma quality control, and strict component screening—this finished injector undergoes a comprehensive manufacturing and testing process to ensure consistent performance and reliability under high-load, high-temperature, high-dust, and high-vibration operating conditions. Its precision-machined, upgraded high-power solenoid design (a premium electromagnetic control component) integrates seamlessly with the engine’s ECM, enabling millisecond-level precise control over injection timing, fuel delivery volume, and atomization effect, which optimizes combustion efficiency, reduces fuel consumption by 8-11%, and lowers harmful exhaust emissions even under long-term full-load operation. Crafted from top-grade high-strength heat-resistant alloy and hardened steel (strictly screened and tested to meet global material standards), the finished 3411767T injector is built to withstand the harshest ultra-heavy-duty operating conditions—sustained high pressure, extreme temperatures (up to 465℃), heavy dust, and diesel fuel impurities. As a direct-fit finished replacement, it requires no installation modifications, perfectly matches the N14 420-450HP engine’s electronic control and fuel supply systems, and each unit undergoes 100% pre-delivery testing (consistent with c-ummins EQA engine quality audit standards, diesel generator set quality inspection specifications, and professional injector performance testing requirements) to ensure trouble-free installation and long-term stable operation. With a net weight of 5kg and standard size, this finished injector comes with original or customized packaging, backed by a 6-month limited warranty, global delivery (3-7 working days), and professional after-sales support, making it the ideal choice for maintaining peak performance in N14 420-450HP-powered heavy-duty trucks, large-scale construction machinery, high-power industrial generators, and heavy mining equipment, delivering exceptional durability, reduced downtime, and consistent high-power output. It also supports flexible customization and provides video factory inspection service to further ensure product quality and customer confidence.
